Thanks -- looks like it's working! For anyone else with this problem, I enabled proposed (as found in https://wiki.ubuntu.com/Testing/EnableProposed), then ran apt install for:
linux-generic/eoan-proposed linux-headers-generic/eoan-proposed linux- image-generic/eoan-proposed linux-libc-dev/eoan-proposed linux-signed- generic/eoan-proposed linux-firmware libasound2 which ended up installing/upgrading: linux-headers-5.3.0-43 linux-headers-5.3.0-43-generic linux-image-5.3.0-43-generic linux-modules-5.3.0-43-generic linux-modules-extra-5.3.0-43-generic libasound2 libasound2-data libasound2-dev linux-firmware I did NOT blacklist snd_soc_skl and snd_hda_intel in the /etc/modprobe.d/blacklist.conf since the comment said "after linux-image-5.3.0-43-generic is ready, the blacklist is not needed anymore". I kept the "options snd-hda-intel dmic_detect=0" that I had previously added to /etc/modprobe.d/alsa-base.conf, didn't try removing it. Sound works again, pavucontrol sees the devices it saw in -40, amixer can control volume again. It still doesn't see the built-microphone, but that's a different bug that I think is targeted for 20.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864061 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1864061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
